Text Performance

Hello, i noticed that Text rendering is fairly slow. I found a work-around by creating bitmap and rendering the text on it once and then rendering the bitmap. This is working but maybe there is another way to have better text rendering performance ?
To be more clear, i'm creating a Node-Based graph and so each nodes may need to have 1 or more text, and this clearly degrade performance when more and more nodes are added.

The issue describes slow text rendering in a node-based graph and mentions a bitmap-rendering workaround, but names no files, tests, or entry points. Start by locating the text-rendering path and comparing performance as nodes and text elements increase. Done would require an agreed rendering improvement and evidence that text performance improves without breaking rendering.
